Thomas covered this pretty thoroughly, and contributed significantly to related threads on other lists, but I want to reiterate the point that the statement above is *not* a rule. Everything after the scheme in a file: URL is OS-dependent by definition. (Thanks, Netscape, for bestowing yet another abomination upon us). The format is: "file:" + an OS-dependent path, properly escaped Ultimately, there are *no* assumptions you can make about what comes after the scheme, if you don't know the OS the URL is associated with. Examples of paths on different OSes that make life difficult: Mac (before OS X) Windows/DOS UNIX ========================= ==================== ================= (no equivalent) \abs\path\to\file /abs/path/to/file drive:abs:path:to:file DRIVE:\abs\path\to\file (no equivalent) :rel:path:to:file rel\path\to\file rel/path/to/file ::foo:rel:path:to:file ..\foo\rel\path\to\file ../foo/etc :::foo:rel:path:to:file ..\..\foo\rel\path\to\file ../../foo/etc (no equivalent) \\Host\Share\abs\path\to\file (no equivalent*) * Well, sorta. Things like NFS, SMBFS, etc. complicate matters a bit The URI resolver shared by Windows Explorer and Internet Explorer is by far the most forgiving. Its ability to handle pretty much anything you throw at it should not be considered evidence of the equivalence of different kinds of path components, or of there being a canonical format for the paths in file: URLs across OSes. - Mike ____________________________________________________________________________ mike j. brown | xml/xslt: http://skew.org/xml/ denver/boulder, colorado, usa | resume: http://skew.org/~mike/resume/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
